The present investigation on “Manifestation of Heterosis in Bitter gourd (Momordica charantia L)” has been undertaken at Central Research Farm, Gayeshpur, Bidhan Chandra Krishi Viswavidyalaya, Nadia, and West Bengal during autumn-winter season of 2015-16 to2016- 2017 aimed to assemblage of diverse inbred lines and development of hybrids, evaluation of the parental genotypes and hybrids through morphological characters, fruit yield components and fruit quality characters, study on the inter-relationships among different characters with a view to ideotype breeding for enhancing fruit yield and quality, analysis of the manifestation of heterosis for different characters and identification of promising hybrids suitable for this growing condition. For this purpose, seven diverse parental lines viz., Kerala white, BG-1346501, Pusa Vishesh, Meghna-2, Itki, Special Boulder and Murhu. And Development of 10 Hybrids by specific crossing programme. Analysis of variance showed significant difference due to genotypes for all the characters for which manifestation of heterosis was calculated. Negative heterosis, which is desirable for days to appearance of first male and female flower, number of node bearing first male and female flower and days to first fruit harvest, were common in most of the crosses. Among 10F1 hybrids, Meghna-2 x BG-1346501 and BG-1346501 x Special Boulder were recorded to be the two best performing F1 hybrids for fruit yield per plant. It is therefore, suggested that these promising parents and crosses may be exploited for further amelioration of yield and yield components in bitter gourd. The selected crosses can be directly utilized as promising hybrids.
